Another Planet Films production which, on the whole, is superior to ISLAND OF TERROR (1966) - in fact emerging, for about two-thirds of its length, as a reasonably compelling and effective bit of sci-fi on QUATERMASS lines (likewise, originating on TV and with the plot's heat-wave angle inspired, perhaps, by THE DAY THE EARTH CAUGHT FIRE [1961]).
However, the appearance of the silly-looking aliens at the climax lets the film down (given the exaggerated horrified reaction, earlier on, of the victims when facing them - as yet unseen by the audience!) but, then, the score, the handling and the performances (with Christopher Lee an unusual and, therefore, interesting 'hero') are, again, above-average for the genre - even if Peter Cushing's 'guest star' role isn't one of his best (despite what Leonard Maltin says in his "Film Guide"!). Still, perhaps the best thing about the entire film is the way it successfully integrates a tension-filled romantic triangle (treated in a remarkable, and unexpectedly, adult manner) - involving Patrick Allen and Sarah Lawson (a married couple in real life!), and the sluttish Jane Merrow - amid the gripping 'invasion' plot.
As with ISLAND OF TERROR, the print utilized for this DVD transfer has undergone no visible restoration - and the film's quality, with respect to its presentation, suffers accordingly! The accompanying Audio Commentary, then - featuring Lee, scriptwriting couple Pip and Jane Baker, and moderator Marcus Hearn - is all over the place, but is certainly animated enough to remain consistently interesting throughout.
